The present study aimed to identify the prevalence of hypertension, diabetes and dyslipidemia among patients with IHD and examine associations between each of them with IHD in a Japanese population. Methods Data were collected from health insurance claims in May 2010 for National Health Insurance beneficiaries aged 40- 79 years in Nagasaki Prefecture, Japan. One sex- and age-matched control was randomly selected for each of 42,236 patients with IHD (International Classification of Diseases, 10th Revision code: I20-25). The prevalence of hypertension, diabetes and dyslipidemia and the number of these risk factors were compared between the patients and controls. Associations between risk factors and IHD were examined using a conditional logistic regression model. Results Over 90% of patients with IHD had at least one of hypertension, diabetes or dyslipidemia. The odds of IHD were 4.5- fold (95% confidence interval [CI]: 4.3, 4.7), 4.2-fold (95% CI: 3.9, 4.6) and 5.3-fold (95% CI: 4.9, 5.7) higher for patients with hypertension, diabetes and dyslipidemia, respectively, compared with patients without any of these risk factors. Patients with several risk factors were at increased risk for IHD. Conclusion Comprehensive risk reduction strategies that encourage a healthy lifestyle and diet and promote the recognition, evaluation and management of conventional risk factors are important to prevent IHD., Acta Medica Nagasakiensia, 57(1), pp.13-18; 2012}, pages = {13--18}, title = {Impact of Hypertension, Diabetes and Dyslipidemia on Ischemic Heart Disease among Japanese: A Case-Control Study Based on National Health Insurance Medical Claims}, volume = {57}, year = {2012} }
